RAILWAY-H EAD.

SPECIFICATION forming part of Letters Patent No. 534,992, dated March 5, 1895. Application filed July 18, 1894.. Serial No. 517,892- (No model.)

To all whom it may concern.-

Be it known that we, JOHN BRADY, Jr., and

HENRY C. SPENCE, of Fall River, county of Bristol, State of Massachusetts, have invented an Improvement in Railway-Heads, of which the following description, in connection with the accompanying drawings, is a specification, like letters and figures on the drawings representing like parts.

This invention has for its object more especially the combination with a railway-head having a coiler, of a simple and efficient stopmotion mechanism whereby, when the coiler can has been properly filled the railway-head will be automatically stopped.

Our improved stop-motion is also so constructed that the head will be automatically stopped when the sliver w-i-nds or laps, as it is called, about one of the fluted drawingrolls, and also should the drawn sliver wind or lap about the calender roll.

Figure 1 is a plan view of the central part of a railway-head, with our improvements added, to enable our invention to be understood, the cover for the drawing'rolls being partially broken out, the parts of the machine to the right of the dotted line m Fig. 3, being omitted; Fig. 2,a partial side elevation and section thereof, to the left of dotted line to Fig. 3; Fig. 3, a partial rear or left-hand end elevation of the machine shown in Fig. 2, with the entire shipper handle and driving belt and pulleys added. Fig. 4, is a partial section to the right of the line m Fig. 3; Fig. 5, a section looking to theleft of the section line a Fig. 4. Figs. 6 and 7, are details showing the main stop-lever, the trip-finger, shipper-bar, and some of their co-operating devices; Figs. 8 and 9, details showing connections between the cover of the drawing-rolls and the slide-rod 30; Figs. 10 and 11, details of the devices between the calender-rolls and the slide-rod 30, Fig. 11 being a partial section in the line 00 Fig. '10. Fig. 12, is a section to the right of the said line 00 Fig. 13, shows two views of the bar 19, tobe described.

The table A; the roller-stand A having suitable bearings for a set of four drawing-rolls a, b, c, d, their actuating gearing; the cover B for said drawingrolls, said cover being hingedat B; the spoon trumpets B having notched arms; the rock-shaft B its arm B to co-operate with the spoon trumpets when an end breaks on its way to the drawing-rolls; the sliver trumpet O; the calender-rolls 0, 0 having their journals supported in bearings of asuitable stand C mounted on the table A; the coiler-top having a gear 2, and the coiler cover 0 and coiler can C the main driving shaft 0 having a fast pulley O and a loose pulley C, the back roll pulley O belted, in practice, with a pulley not shown, on the'main driving shaft; said pulley 0 being on a short shaft having at its inner-end a gear 3, to engage a gear 4 on the lower back roll, are and may be all as usual, and in practice the coilertop will be rotated in the usual manner. For use with these old parts we have devised a stop-motion mechanism, which we will now describe.

Referring first to the gear at on the lower back roll, it engages an intermediate gear 6 adapted to rotate about a stud made adjustable in a quadrant-shaped slot, shown by dotted lines Fig. 2, in a stand 5 which we have erected on the table A, said stud being made adjustable in order to provide for adjustment of the drawing to the length of'the staple being used.

The intermediate gear 6, see Fig. 2, engages a toothed gear 7 fast on a short shaft 8 mounted in a stand 10, said shaft having at one end a crank 12 (see Figs. 4 and 5), or its equivalent, an eccentric. The crank 12 enters a hole in one arm of a link 13 having a stud 14 and jointed loosely at 15 to a rockerlink 16 mounted loosely on a stud 17 connected to the table A, said rocker-link serving to steady the link 13 in its movements. This stud 14 enters a diagonal slot 18 in a bar 19 journaled at 20 to an arm 21 fast to the rock-shaft B before, described. This rock-shaft has been provided by us with a third or stop arm D, the rotation of the crank in the regular working of the machine rocking the shaft B (Jo-operating with this stop arm is what we shall denominate the main stop lever D, the shape of which is best shown in Figs. 2, 4. and 7, said lever being pivoted at 22 on a stand 23 secured to the table A, by a bolt 24, the upper end 25 of said lever being the heavier, and havinga too 26. When the machine is running regularly, the said toe rests on a lug 27 of a trip-finger 28 pivoted at 29 on a part of the said stand 23,

said finger having a Weighted portion 28 which acts normally to keep the lug end of the finger pressed toward the table A and under the said toe.

The trip-finger has jointed to it a rod 30, which, at its other end is jointed to the upper end of an arm 31 fast to a rock-shaft 32 having its bearings in a stand 34 bolted to the top casing 35 of the coiler, said casing being as usual.

The rock-shaft 32 has a finger 33 which overlies the usual rotating coiler-top C, so that when the coiler can has been properly filled and the said top begins to rise, due to a sufiicient quantity of material, it acts on said finger, turns the rock shaft, and causes the rod to be moved to the left, viewing Figs. 1 and 2, thus moving the trip-finger from below the toe of the main stop-lever, so that the heavier or weighted end of said lever drops, thus elevating its opposite end in the path of movement of the stop-arm D, as represented by dotted lines in Fig. 7, thus stopping the further rotation of the rock-shaft B When the rock-shaft is stopped, as stated, while the crank 12 continues to rotate, the parts would break were it not for the stud 14 slipping in the slot 1S of the arm 19.

The belt E for driving the main shaft is shown in Fig. 3, as on the fast pulley and as embraced by the usual forked part of the shipper lever E pivoted at E the said lever above said point being slotted at 34, see Fig. 3, to receive a pin fast on the shipper-bar E adapted to slide longitudinally in suitable guide-ways 36 attached to the table A.

The shipper-bar has adj ustably connected with it a lifting shoe 37, and at a distance therefrom is provided with a locking notch 38, the end of the bar having a suitable stud 39 which engages the upper end of a forked lever 40 having a projecting pivot 41 which enters a hub 42 of a stand 43 secured to the table A,t he lower end of said lever being embraced, see Figs. 2 and 3, by the forked arm 44 of the usual upright shipper-shaft 45 mounted in a bearing 46 secured to the under side of the said table. The shipper-bar has a stud 47, which has connected to it one end of a suitable spring 48, the opposite end of the spring being connected to a suitable hook on the table A, the said spring acting normally to keep the shipper-lever in position to retain the belt on the loose pulley.

The-locking device consists essentially of wedge-like block 49 attached to a finger 5O pivoted at 50 on a lever 51, in turn pivoted at 52 on a stand 53 secured to the table A, said lever 51 being acted upon by a spring 54, one end of which is attached to a suitable hook on the stand 53, so that the said spring normally acts to keep the block 49 in the notch 38 of the bar E The block 49 and finger 50 constitute a locking device for the bar E The finger 50 is slotted for the passage through it of the bar 19, and the upper end of the finger enters a guide 56.

When the locking device is lifted by the rising of the bar 19, as before described, after the arrest of the stop-arm D, the said locking device releases the shipper-bar and lets the spring 48 act to move the said bar, turn the shipper-lever and put the belt E on the loose pulley. In case the sliver or end winds or laps about one of thedrawing-rolls, the said rolls will be separated and the cover B will be lifted through the bar 57 and screws 58, we having interposed this bar and screws, see Figs. 2 and 8, to enable the drawing-rolls to be changed for those of a different diameter, as from one and one-eighth to one and onehalf and yet enable the cover to operate properly with stop-motion devices, which we shall now describe.

One end of the cover B, see Figs. 2 and 8, when the rolls are not wrapped or lapped with sliver, rests on the upper end of a plunger fjointed at f to a short arm f of a lever F pivoted atf on a stand f the long arm of said lever being, asrepresented, heavily weighted, so that the lever normally acts to lift the plunger. This lever F has a third arm or projection f bent backwardly to cross the rod 30 and contact with a pin 59 on said rod, so that said rod is moved to the left, viewing Figs. 1 and 2, to move the trip-finger 28, as before described, and release the main stop-lever, but this time due to the accumulation of fiber on a drawing-roll. The plunger is kept in line by a suitable guide 60 attached to a stand f.

The journal of the upper calender-roll C is embraced, as shown, by the hooked end of a link g, see Figs. 2 and 11, jointed at 61 to one end of a lever g pivoted at 62 on the stand 34, the upper end of said lever resting normally against a pin or projection 63 of the rod 30, said lever moving said rod to the left, as before described, when sliver winds or laps about a calender-roll sufficiently to lift the same far enough to turn said lever, the sliding of the said rod to the left, as before described, effecting the stopping of the main shaft.

From the foregoing it will be understood that the main shaft may be stopped auto matically whenever either the coiling can becomes full, or the sliver breaks before reaching the rolls, or if the sliver winds or laps about either one of the drawing-rolls or a calendering roll.

The filled can having been removed and another supplied, or the error or fault which caused the machine to be stopped having been corrected, the operator will engage the shipper-lever E and turn it in the direction to put the belt E on the fast pulley, and in doing this another part of our invention comes intov play, viz:.the lifting shoe 37 acts against the under side of the main stop-lever and lifts its heavier end so that the toe thereof is placed on the lug 27 of the trip-finger, leaving the parts set in their working position.

Thisinvention is not limited to the exact shape, of. the stop motion devices shown, as we are not aware that prior to our invention any machine having drawing-rolls, calenderrolls, and a coiling mechanism, has ever had combined with it a mechanical stopmotion to automatically stop the machine on the completion of one operation and error in normal condition of two other operations, nor are we aware that a series of devices have ever been combined with one single slide-rod, as 30, to effect the stopping of the main shaft under conditions such as specified; nor are we aware that a single operation of the operator has been sufficient to restore to normal working condition devices capable of being thrown out of normal condition by several different occur rences.
